AIR-HEATING DEVICE FORSUPPLYING HEATED AIR To BUILDINGS non CURINGTOBACCO. y i

Application filed October 8, 1919. Serial No. 329,260.

To all whom it may concern:

Be it known that I, JOHN B; liflusn, a

citizen of the United States, residin at Cameron, in the county of Mooreand State of North Carolina, have invented certain new andusefullmprovements in Air-Heating Devices for Supplying Heated Air toBuildings for Curin Tobacco, of whlch the following is a specification,reference being had thereinto the accompanying drawings.

This invention relates to a tobacco curing apparatus, and has for itsobject the 1mprovement of the construction of a furnace and itscooperating parts, whereby a comparatively small furnace can eflicientlyheat a large building by reasons of the novel structure ofthe furnaceand its necessary cooperating pipes or flues.

Another obJect of the invention is the production of a tobacco curingapparatus which will evenly distribute the hot air throughout thebuilding by reason of the peculiar positioning of the pipes, as well asother peculiar construction.

With these and other objects in view, my invention comprises certainother novel com binations, arrangements and constructions as will behereinafter specifically described, illustrated in the accompanyingdrawings, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a perspective view of the furnace or stove of my improvedapparatus, while-- Fig. 2 is a longitudinal section of the same.

Fig. 3 is a sectional View taken on the line 3-3, Fig. 2, and looking inthe direction of the arrows.

Fig. 4 is a section taken on the line t e, Fig. 2, looking in thedirection of the arrows.

Fig. 5 is a plan view of the preferred embodiment of my apparatus.

Referring to the drawings by numerals, 1 designates a portion of abuilding in which tobaccco is to be stored for curing, and preferably atthe front end 2 of the building 1 (Fig. 5) are positioned two furnaces3. In Fig. 5 I have shown a diagram of two tobacco apparatuses, but itwill only be necessary to specifically describe one, as they aresubstantially duplicates.

The furnace 3 comprises a body having sides 1 and at the bottom ofthebody is formed an ash pit 5; the body (Fig. 3) is supported uponbricks6. The sides 4, com tiguous to thcash pit 5 are provided with inwardlyextending flanges 7, which flanges support grate bars 8. At the upperedge of each 'side 4 is an outwardly extending flange 9. v

The top of the furnace comprises an inner curved plate and an uppercurved plate 11. The edges of the inner plate 10 rest upon the top ofthe sides 4, (Fig. i) and the edges of the outer or upper curved plate11 are flattened to form flanges 12, which flanges 12 fit snugly uponhorizontal flanges 9 and these flanges are fastened together by suitablerivets or bolts 13. The outer plate 11 of the top of the furnace iscorrugated, as at 14, intermediate its ends to provide a greaterradiating surface. Between plates 10 and 11 is formed a hot aircompartment 15. Near the front end of the outer plate 11 is an air inletopening surrounded by a nipple 16 upon which is mounted a curved freshair pipe 17, which pipe 17 is provided with a suitable valve 18 forcontrolling the passage of fresh air into the hot air compartment 15. r

A hot air pipe 19 has its inner end on a nipple on the top of the late11 near its inner end within the building 1 and within the hot air pipe19 is placed a plurality of small or auxiliary hot air pipes'20, whichcommunicate with the compartment 15, the

inner ends of some of the pipes 20 rest against the top edge of thenipple engaged by pipe 19, and in the primary or outer pipe 19 areformed corresponding apertures 20*, one being the outlet for eachauxiliary pipe 20 (Figs. 1 and 2) so that hot air is passed from the hotair compartment through the auxiliarypipes into the building atdifferent points or locations, and some heated air is also dischargedfrom the end of pipe 19, which end terminates short of the front 2 ofthe buildingl, as shown in the diagram building, discharging into asuitable stack 22. This smoke pipe 21 also serves to heat some of theair in the building 1.

lVhile I have described the preferred embodiment ofmy invention and haveillustrated the same in the accompanying drawings, rertain minoralterations or changes may he found desirable in the extensivemanufacture of my apparatus, and therefore, I reserve the right to makesuch alterations or changes as shall appear to one skilled in the art toWhich this invention relates, and which fairly fall within the scope ofthe appended claim.

" What I claim iszi v A device of the kind described consisting of afurnace provided With a top including a top plate having a nipple formedthereon,

said furnacevprovided with a hot air compartment under said top plate, afresh air pipe communicating at one end with said hot air compartment, acurved or bent primary'hot air pipe positioned at one end upon saidnipple, a plurality of auxiliary hot air pipes within said primary hotair pipe and filling the same and some having their inner ends restingagainst the top edge of the nipple, and said primary hot air pipe havinga number of side discharge openings or apertures corresponding to theauxiliary primary hot air pipes, each auxiliary pipe having its endcommunicating with a side opening, and the primary hot air pipe beingleft free to discharge hot air near one end.

In testimony whereof I hereunto afiix my signature.

JOHN B. MUSE.
